Letters ,Patent No. 94,879, dated September 14, 1869.

IMPROVEMENT IN sEcTroNfRoi- QLER ANE MARKER COMBINED- The Schedulereferred to in these Letters Patent and making pari: oi the same.

following is a ,'full, clear, and exact descriptionof the constructionand operation of the same, reference being had to the accompanyingdrawings, making a partof this specification, in which` l Figure 1 is alongitudinal vert-ical section through line :uw of fig. 2'.V

Figure 2 is a top view.

This invention consists in` a new arrangement and combination ofsection-rollers and section-markers in a single instrument, tobeejnployed on plowed ground in rolling the surfaceand laying oiiwell-defined drills or channels, at any required distance apart,into'which the agiiculturist can lead water and thereby distribute ituniformly over the field for the purpose of irrigation. The instrumentis designed, and its forni and con# struction has a special adaptationfor use on the lands along the eastern slope of the Rocky mountains andCordilleras, in Colorado and -New' Mexico, which require irrigationalmost every season.

In the drawings- A is the frame, B, the draught-pole, and c, the axle. vR R are section-rollers, each running loosely on the axle, andindependently of all the others.

'M M are section-markers, interposed between the rollers, and havingtheir sharp Wedge-form edges projecting beyond `the perimeter of therollers, as shown in fig. 2, and so constructed as to imprint vupon thesurface of the ground long well-defined parallel drills `or channels,several inches deep, and with pressed and hardened sides and bottom. v

These channels may be varied in distance from each otherby removing someof the markers, or by substituting longer or shorter rollers betweensaid markers.

i' By this means,'the agriculturistcan mark the surface of his ground(which in thc country referred to is gen? erally slightly inclined) withseries of parallel channels, at any suitable distance, from a few inchesto tivo or three feet apart, and then by introducing water intothesechannels at their upper end, it willfbe conveyed to all parts of theiield, and broughtl to every squat-.e1

'foot of soil tlierein.-

The means for introducing the Water at .the upper end of the-channelsmay simply be a small canal o' trench ruiming at angles to the drillsabove described.

'When not used thusto lay off the surface of the field into suitablewater-channels, the markers may be removed, and vtheinstrument-usedwithout them,as an ordinary field or lawn-roller.

The rollers and markers being made in sections, or independent of eachother, the instrument is not only adapted to make the channels atdi'erent distances apart, as may b e required, but it turns more easilyat the ends lofthe eld than if the roller-sand markers were made in oneor two solid pieces; and besides these two advantages, it can be takenapart and packed lfor transportation into a much more compact andconvenient form for handling.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, .is-

The section-rlier and marker for irri gatin g-purposes, substantially asabove described, having the frame A, draught-pole B, short independentrolls R R, and interposed markers M M, rot-ating independently of eachother and of the rolls, when constructed in themanner herein set forth,and for the purposes specified.

To the above specification of my improvement, I

have set myA hand, this 13th day of April, 1869.
